It specifically indicates the end of the no overtaking prohibition for trucks that was previously established by sign R-From the location of this sign onwards, trucks with a Maximum Authorized Mass (MAM) exceeding 3,500 kg are permitted to resume overtaking maneuvers, provided that road conditions and general regulations allow it. It should not be confused with the 'End of all local prohibitions' sign (R-500), which is blank without silhouettes, nor does it apply to road users other than trucks.
